Have you seen the new entries to the Online Oxford English Dictionary? They are only online and not in the OED per se. I enter them here because to me they are slang and largely geek slang from electronics. Most are not in most Agora denizens vocabulary, but I bet some will creep in. As I mentioned elsewhere, I.ve started to use "dongle."

Nice catch. But I could argue with several of them, since app to me is not synonymous with applet. App refers to the program, whereas applet refers to the icon to call up the program. The latter comes from Apple, while app is short for application. Or so I have used it.
